WORK OF REPLACEMENT OF 132 KV MAIN BUS FROM ACSR SINGLE TARANTULA CONDUCTOR TO ACSR TWIN MOOSE CONDUCTOR AGAINST AUGMENTATION OF 220 KV S/S AMROHA UNDER ETD AMROHA

Annexure A (Work) Cutting/Opening of single Tarantula conductor cross jumper among the three sections of each phase of existing 132 KV main bus and shifting of the recovered material from site to store.

Cutting/Opening of single Zebra/Panther Conductor jumper/ dropper of each phase of existing 132 KV main bus to bus isolator, shifting of material from site to store. There are 10 nos. 132 KV bays, each bay have 01 No. bus isolator and 03 Nos. of jumper/dropper. Thus total Nos. of jumper/droppers 10x3=30. (40 MVAR Bus side isolator jumper -03 Nos)

Cutting/Opening of single panther conductor from Bus isolator to 132 KV Circuit Breaker and shifting of the recovered material from site to store.

Dismantling of existing single Tarantula conductor of each phase of 132 KV main bus & shifting of the recovered material from site to store. There are 04 Nos. sections having 03 Nos. conductores in each sections.

Stringing of Twin moose conductor of each phase of 132 KV main bus with the help of single tension twin moose fitting alongwith spacers, hoisting of Disc insulators and other hardware at both ends of span & proper sagging including cutting, bending of conductor to & for shifting of the material from store to site. Each bus has 03 spans having 03 Nos. of twin moose conductors.Total nos. of section conductors. 4x3=12

Reconnection of Twin Zebra/ Panther jumper/dropper between each phase of 132 KV main bus and bus isolator including cutting bending of conductor alongwith spacers to & for shifting of material from store to site. There are 10 Nos. 132 KV bays, each bay have 01 No. bus isolator and 03 Nos. of jumper/dropper Thus total Nos. of jumper/droppers= 10x3=30.(40 MVAR Bus side isolator jumper -03 Nos)

Reconnection of Twin Zebra/Panther jumper from Bus isolator to 132 KV Circuit Breaker.

To connect twin moose cross jumpers with spacers, P.G. clamps etc. among three sections of newly stringed 132 KV main bus including cutting, bending of conductor, shifting of material from store to site. There are 04 sections having cross jumpers at three places. Total No. of crosss jumpers =3x3=9

Dismantling of 132 KV Single Zebra Conductor completely after opening of jumper and disconnecting complete dismantling work including shifting of the recovered material from site to store. (a) 160 MVA 220/132 KV T/F-I and II bay jumpering work. (b) 40 MVA 132/33 KV T/F-I & II bay jumpering work. Thus total no of jumpers is 6 nos. so 6x3x2bays=36

Stringing of twin Zebra conductor of each phase of 132 KV bay with the help of required hardware at both ends of span & proper sagging including cutting, bending of conductor, connection of twin jumpers/droppers in between jack bus & CB,LI, LV terminal, CT, LA & shifting of the materail from store to site for jack bus (a) 160 MVA 220/132 KV T/F-I and II bay jumpering work. (b) 40 MVA 132/33 KV T/F-I & II bay jumpering work. Thus total no of jumpers is 6 nos. so 6x3x2bays=36
